I've seem sometimes people saying that although uniform motion on a straight line cannot be detected and hence it is not absolute, acceleration is indeed absolute in Classical Mechanics (I don't know ...

I've tracked the movement of an input method resulting in this dataset. All data is tracked with equal intervals of 100ms. For example an iteration value of 4 means that this is the position of the ...

So in order for two things $A$ and $B$ to move apart, for example, relative to each other, $B$ can be set into motion away from $A$. This means that we have to increase $B$'s velocity and therefore ...

I would like to measure and compare the accuracy of different accelerometers.
Obviously I must choose a reference, therefore I compare all the accelerometer with this reference and then decide which ...

I am a martial arts instructor always looking for the next best way to enhance the performance of my students. However, I'm having difficulty understanding how to determine the pound-force (ibf) of a ...

I'm not sure this belongs in this StackExchange, but I wasn't sure where else to put it. It seems average human walking speed is about 1.4 m/s, but I was wondering what average human acceleration was.
...

My issue
I have the mass of a body and the force that is acted on a body. I am trying to calculate the horizontal acceleration and to understand how the horizontal acceleration is connected with the ...

Let's have a ship, a target and a ship traveler which we use as point of view. Assuming no other object are observed and we are so far from any other object that gravity distortion are negligible, I'm ...

In my textbook there is a case given that is to find acceleration and tension produced in a string passed over a frictionless pulley and attached with bodies of different masses at its ends. Now below ...

I have read that in the Schwarzschild spacetime for a nongeodesic circular orbit the radial acceleration becomes positive for $r<3r_S$. Intuitively, the acceleration should be negative, pulling the ...

According to multiple websites, any object in free-fall (no air resistance) on earth will accelerate towards the Earth at 9.8 m/s. If all objects fall towards the Earth at the same rate, regardless of ...

Can you have a zero velocity and nonzero average acceleration?
I am confused with the word "average" here. If the question would be, "Can you have a zero velocity and nonzero acceleration?" my answer ...

If something is caught in the pull of a black hole and keeps accelerating it can't keep accelerating with no limits or else it would accelerate beyond c. So is there a limit on how fast acceleration ...

I intend to design an application for Android which uses the accelerometer to detect the acceleration. However I'd also like to use the magnetometer to reduce the noise from accelerometer readings.
My ...

A wheel of radius $R$ spins about its center with a centripetal acceleration of $v^2/R$.
I get that the acceleration at all points on the rim of the wheel point towards the center of the wheel. But, ...

Is acceleration law
$a = \Delta v/\Delta t$
applicable on somebody who is falling from an air plane? Does the acceleration increase when some body is at some altitude and does his speed increases by ...

This seems a very simple question - and I guess it will turn out to be so. It's a given that accelerating particles with mass towards the speed of light takes more and more energy (ultimately an an ...

Suppose you have some object (which can roll like a ball,cylinder,wheel,etc) rolling down an incline without slipping (moment of intertia $I=kmr^2$. I want to find the accleration of the ball as it ...

I am doing physics homework and I noticed that the solution to this question specifies that the total vertical Force is 0. Since the two buckets (shown below) are hanging vertically, wouldn't I just ...
